Abstract:
Cut steel wire shot is often used for shot peening treatments. A CW32 shot was used in this study. Surface roughness and produced residual stresses were checked during the
shot peening process in order to determine the influence of ageing, wear, evolution of diameter, scattering of hardness and modification of the shots. The breaking and
wearing modes have also been studied.
T
he results obtained show the good quality of this type of shot for
shot peening, in comparison with cast steel shots, provided that the cut steel wire shot has been submitted to prior light shot peening before use (prior conditioning).
